• 500x = £500

The Latest Bonus Buy Slot Releases

1️⃣ Oxygen 3

Developer: ELK Studios
Volatility: High (7/10)
Max Win: 25,000x
RTP: 96%
Bonus Buy RTP: 98.40%
Release Date: 7th April 2026

The team at IEH Consulting think Oxygen 3 is a solid continuation of the series, keeping the addictive multiplier mechanics that fans love while adding a darker, more atmospheric twist. It doesn’t feel like a huge leap forward, but the new features and improved RTP keep it engaging. Overall, it’s a strong high volatility slot with good win potential, even if it doesn’t quite match the freshness of the original.

2️⃣ Munchy Milo

Developer: Hacksaw Gaming
Volatility: Medium-High (6/10)
Max Win: 10,000x
RTP: 96.30%
Bonus Buy RTP: 99.10%
Release Date: 9th April 2026

We think Munchy Milo is a fun and quirky slot with a creative theme with the Jolt Frames and Chain Reaction mechanics the main highlight and can create some exciting moments when everything connects, especially with wild multipliers in play. However, despite the entertaining visuals and solid gameplay, it doesn’t bring much new to the table, making it enjoyable but not particularly innovative.

3️⃣ Jelly Express

Developer: Pragmatic Play
Volatility: High (9/10)
Max Win: 5,000x
RTP: 96.50%
Bonus Buy RTP: 98.90%
Release Date: 30th March 2026

Jelly Express is a solid, high energy slot that blends familiar elements from games like Sweet Bonanza and 5 Lions,making it instantly accessible. The multiple free spins options and wild multipliers add flexibility and excitement, especially in the super free spins mode where things can really ramp up. The 5,000x max win feels a bit limited compared to similar high volatility slots, so overall it’s an enjoyable experience but not a standout in a crowded genre.
